| 英文摘要 | The poly(vinyl alcohol)/ poly(N-vinyl pyrrolidone) (PVA-PVP) hydrogels containing silver nanoparticles were prepared by repeated freezing-thawing treatment. The silver content in the solid composition was in the range of 0.1-1.0 wt %, the silver particle size was from 20 to 100 nm, and the weight ratio of PVA to PVP was 70 : 30. The influence of silver nanoparticles on the properties of PVA-PVP matrix was investigated by differential scanning calorimeter, infrared spectroscopy and UV-vis spectroscopy, using PVA-PVP films containing silver particles as a model. The morphology of freeze-dried PVA-PVP hydrogel matrix and dispersion of the silver nanoparticles in the matrix was examined by scanning electron microscopy. It was found that a three-dimensional structure was formed during the process of freezing-thawing treatment and no serious aggregation of the silver nanoparticles occurred. Water absorption properties, release of silver ions from the hydrogels and the antibacterial effects of the hydrogels against Escherichia coli and Staphylococcus aureus were examined too. It was proved that the nanosilver-containing hydrogels had an excellent antibacterial ability. (C) 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 125-133, 2007 |
